中文摘要:

      目的 通过对当前市场中的PET、PP、PE3种主流塑包材质包装的山茶油中的邻苯二甲酸酯类增塑剂（PAEs）残留进行监测，旨在全面了解市售山茶油中增塑剂残留状况与危害水平，为山茶油安全包装提供技术依据。方法 模拟商品货架的摆放条件12个月，应用凝胶渗透色谱--气相色谱质谱法对山茶油中的PAEs迁移水平进行定期监测。 结果 山茶油中存在着微量的PAEs存在，其主要成分为邻苯二甲酸二丁酯（DBP）与邻苯二甲酸二(2-乙基)己酯（DEHP）。结论 在山茶油品质保持期内，以上3种主流塑包材质包装的山茶油中的PAEs特定迁移量均低于国家卫生部的限量规定，正常生产条件下山茶油加工企业引用上述塑包材质是安全的。

英文摘要:

      Through detecting the residue levels of phthalic acid esters(PAEs) in camellia oil packaged with 3 different plastic(PET、PP、PE) in the current market , our goal was to know plasticizers residues and hazard level in camellia oil and provide technical basis for camellia oil safety packaging. Methods Simulating the condition of store shelves for 12 months, migration law of PAEs was studied by the use of gel permeation chromatography and gas chromatography-mass spectrometry. Results The migration levels of PAEs in camellia oil packaged with different plastics (PET、PP、PE) were lower than national standard during the shelf life, which meant it was safe to package camellia oil with these plastics for camellia oil processing enterprises under the condition of normal production.
